It sounds like we have different goals. I just wanted access to the TTL-level UART signals TX, RX, and GND. If you want access to the JTAG signals you will have to go to a lot of hassle to *maybe* save $10 over the official JTAG connector that Global Scale offers.

We just looked at the datasheet for the crimper which shows in detail how the connectors should be crimped and carefully copied that by bending the connectors with tiny flat blade screwdrivers and hemostats. Good luck!

I didn't pay for the overpriced JTAG box that Globalscales sells as an option with the GuruPlug. Now I'm trying to get serial console access to the 4-pin 3.3V UART connector. Has any one been successful in finding a male connector for this port (e.g. on Digikey)? If anyone has a hi-res photo of the actual UART connector that comes on the official JTAG breakout box, that would be very helpful!
